Add a post build hook
2019-08-02 Add a test for auto-GCEelco Dolstra2-1/+62
This currently fails because we're using POSIX file locks. So when the garbage collector opens and closes its own temproots file, it causes the lock to be released and then deleted by another GC instance.
2019-08-02 Add a post-build-hookregnat4-1/+22
Passing `--post-build-hook /foo/bar` to a nix-* command will cause `/foo/bar` to be executed after each build with the following environment variables set: DRV_PATH=/nix/store/drv-that-has-been-built.drv OUT_PATHS=/nix/store/...build /nix/store/...build-bin /nix/store/...build-dev This can be useful in particular to upload all the builded artifacts to the cache (including the ones that don't appear in the runtime closure of the final derivation or are built because of IFD). This new feature prints the stderr/stdout output to the `nix-build` and `nix build` client, and the output is printed in a Nix 2 compatible format: [nix]$ ./inst/bin/nix-build ./test.nix these derivations will be built: /nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv building '/nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv'... hello! bye! running post-build-hook '/home/grahamc/projects/github.com/NixOS/nix/post-hook.sh'... post-build-hook: + sleep 1 post-build-hook: + echo 'Signing paths' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: Signing paths /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: + sleep 1 post-build-hook: + echo 'Uploading paths' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: Uploading paths /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: + sleep 1 post-build-hook: + printf 'very important stuff' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation [nix-shell:~/projects/github.com/NixOS/nix]$ ./inst/bin/nix build -L -f ./test.nix my-example-derivation> hello! my-example-derivation> bye! my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + echo 'Signing paths' /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> Signing paths /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + echo 'Uploading paths' /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> Uploading paths /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + printf 'very important stuff' [1 built, 0.0 MiB DL] Co-authored-by: Graham Christensen <graham@grahamc.com> Co-authored-by: Eelco Dolstra <edolstra@gmail.com>

2019-05-03 Add builtins.hashFileDaniel Schaefer7-1/+11
For text files it is possible to do it like so: `builtins.hashString "sha256" (builtins.readFile /tmp/a)` but that doesn't work for binary files. With builtins.hashFile any kind of file can be conveniently hashed.

This can be very helpful when debugging, as well as enabling complex black magic like surgically removing a single dependency from a string's context.
2018-12-14 tests/fetchurl: fix after changing default hash from 512 to 256Will Dietz1-1/+1
2018-12-13 Support SRI hashesEelco Dolstra2-1/+22
SRI hashes (https://www.w3.org/TR/SRI/) combine the hash algorithm and a base-64 hash. This allows more concise and standard hash specifications. For example, instead of import <nix/fetchurl.nl> { url = https://nixos.org/releases/nix/nix-2.1.3/nix-2.1.3.tar.xz; sha256 = "5d22dad058d5c800d65a115f919da22938c50dd6ba98c5e3a183172d149840a4"; }; you can write import <nix/fetchurl.nl> { url = https://nixos.org/releases/nix/nix-2.1.3/nix-2.1.3.tar.xz; hash = "sha256-XSLa0FjVyADWWhFfkZ2iKTjFDda6mMXjoYMXLRSYQKQ="; }; In fixed-output derivations, the outputHashAlgo is no longer mandatory if outputHash specifies the hash (either as an SRI or in the old "<type>:<hash>" format). 'nix hash-{file,path}' now print hashes in SRI format by default. I also reverted them to use SHA-256 by default because that's what we're using most of the time in Nixpkgs. Suggested by @zimbatm.

2018-10-27 Restore old (dis)allowedRequisites behaviour for self-referencesEelco Dolstra3-1/+5
stdenv relies on this. So ignore self-references (but only in legacy non-structured attributes mode).
2018-10-23 Per-output reference and closure size checksEelco Dolstra1-1/+1
In structured-attributes derivations, you can now specify per-output checks such as: outputChecks."out" = { # The closure of 'out' must not be larger than 256 MiB. maxClosureSize = 256 * 1024 * 1024; # It must not refer to C compiler or to the 'dev' output. disallowedRequisites = [ stdenv.cc "dev" ]; }; outputChecks."dev" = { # The 'dev' output must not be larger than 128 KiB. maxSize = 128 * 1024; }; Also fixed a bug in allowedRequisites that caused it to ignore self-references.

2018-08-17 fetchGit: use a better caching schemeGraham Christensen1-2/+2
The current usage technically works by putting multiple different repos in to the same git directory. However, it is very slow as Git tries very hard to find common commits between the two repositories. If the two repositories are large (like Nixpkgs and another long-running project,) it is maddeningly slow. This change busts the cache for existing deployments, but users will be promptly repaid in per-repository performance.

Fix symlink leak in restricted eval mode
2018-08-03 Fix symlink leak in restricted eval modeaszlig1-0/+11
In EvalState::checkSourcePath, the path is checked against the list of allowed paths first and later it's checked again *after* resolving symlinks. The resolving of the symlinks is done via canonPath, which also strips out "../" and "./". However after the canonicalisation the error message pointing out that the path is not allowed prints the symlink target in the error message. Even if we'd suppress the message, symlink targets could still be leaked if the symlink target doesn't exist (in this case the error is thrown in canonPath). So instead, we now do canonPath() without symlink resolving first before even checking against the list of allowed paths and then later do the symlink resolving and checking the allowed paths again. The first call to canonPath() should get rid of all the "../" and "./", so in theory the only way to leak a symlink if the attacker is able to put a symlink in one of the paths allowed by restricted evaluation mode. For the latter I don't think this is part of the threat model, because if the attacker can write to that path, the attack vector is even larger. Signed-off-by: aszlig <aszlig@nix.build>
